Exactly. Additional spaces are ignored in HTML when it is parsed and
displayed in the browser. Otherwise any spaces used for formatting your
code would appear in the browser and it would be an almighty mess.

If you look at the source code of the generated page (View|Source) you
should see the spaces there.

If you are wanting to right align columns of numbers you are best to use
a table with the cell align property set eg:

<table>
<tr>
<td align="right">1.23</td>
<td align="right">543.77</td>
<td align="right">23.45</td>
<td align="right">8756.00</td>
</tr>
</table>
